To start with which ones are they:
The holster on the right is the Viper
The holster on the left is the FlatJack
Now with both holsters it is clear they were made with quality materials and are very well stitched together. While this is a step in the right direction the Flatjack, in spite of it's unassuming appearance, is without question the most comfortable holster I've ever worn. It fits both my weapon and my rather round form so well that I actually forgot I was carrying on several occasions today.
The viper on the other hand while a gorgeous piece of leather-work was a little less one sided as to how I perceived it although I do plan to try it with different attire before making a final judgement on it. Using a 2" reinforced duty belt the loop on it's back fit the belt perfectly and my Ruger GP100 fit the holster itself like a glove. That is the good news. The one and only downside I have found with this holster so far is that the loop is small enough that there is quite a bit of moving around by the holster as it is being worn.
Overall my initial impressions from 1 day of use with these holsters is the flatjack is basically perfection for someone who prefers an OWB conceal carry option and the Viper is a work of art that I need to use more before I decide how I feel about that tiny retention loop.
